Siberia has undergone dramatic climatic changes due to global warming in recent decades. Yet, the ecological responses these are still poorly understood a lack of data. Here, we use unique data set from Russian ‘Chronicles Nature’ network analyse long-term (1976–2018) phenological shifts leaf out, flowering, fruiting and senescence 67 common Siberian plant species. We find that boreal forest pl...
An undesirable sensory attribute (“floral taint”) has been detected in red wines North America, caused by leaves and petioles (materials other than grapes [MOG]) introduced during mechanical harvest after killing frosts. From 2017 to 2019, several strategies were evaluated on Ontario Cabernet franc: hand (HH), conventional machine harvesting (MECH), Braud-New Holland Opti (OPTI), Gregoire GL8, ...
The article presents the results of studying productivity parameters introduced apple variety Majesti on clonal rootstock M9 in agro-ecological conditions southeastern foothill sub-province Dagestan. purpose research is to identify biological potential variety, adaptive for construction intensive-type orchards industrial horticulture zone. It especially important choose optimal variety-rootstoc...
Relevance. Pumpkin is a food, medicinal and fodder crop of the Cucurbitaceae family. It valued for its high content vitamins, minerals, organic acids. At present, thanks to huge variety species modern selection, it possible select pumpkin varieties cultivation in almost any region, including areas with short not too hot summers. Udmurtia belongs zone risky farming, end spring frosts observed on...
Spring frosts can defoliate trees, reduce canopy carbon assimilation, and alter interspecific competition dynamics. These events may become more common with climate change, but our understanding of the associated ecological impacts is limited by stochastic nature their occurrences. In 2020, a late spring frost defoliated oak ( Quercus spp.), not co-occurring maples Acer spp.) across temperate b...
High-yielding crops with C4 photosynthesis arising in tropical climates are being bred for, and increasingly grown in, temperate climates. Miscanthus, a from Eastern Asia is leading perennial biomass crop, but commercial deployment limited by low temperatures Northern Europe, clonal multiplication rates slow establishment requiring up to 4 years reach mature yields. While new seeded hybrids hav...
Black currant is the most valuable berry crop of Murmansk Province in terms both biological properties and adaptive qualities necessary for growing difficult agroclimatic conditions North. Every year, a search carried out varieties forms with best indicators winter hardiness, yield, disease resistance environmental friendliness, order to identify accessions economic traits. The objects present ...
Performing agricultural analysis is becoming much more effortless due to the rapid improvements in information technologies. Geographic Information Systems (GIS) provide detailed data about climate, soil, topography, and irrigation values regarding agriculture; thus, allowing for performing location analyses. These analyses cover investment maps, propriety areas, plant pattern detections. The p...
Scree forests with large numbers of protected plants and wildlife are seriously threatened by climate change due to more frequent drought episodes, which cause challenges for very stony, shallow soils. The effect environmental factors on the radial growth five tree species—European beech (Fagus sylvatica L.), Norway spruce (Picea abies (L.) Karst.), sycamore maple (Acer pseudoplatanus European ...
